CHRONO
Privacy Policy · Effective 9 November 2026
1. WHO WE ARE
Chrono is a stopwatch and countdown timer application for Android, published by KaiDevLab (Ahmed Husrev Dereli). This policy covers the Chrono app, package name io.kaidev.chrono.
2. DATA WE COLLECT
None. Chrono does not collect or process personal data. Specifically, the app does not collect:
- Names, email addresses, phone numbers or account information
- Location data
- Contacts, calendar, photos, files or SMS
- Camera or microphone data
- Device identifiers or advertising IDs
- Usage analytics, crash reports or diagnostics
3. DATA STORED ON YOUR DEVICE
Timer values and lap times exist only in the app's memory while it is running. Chrono does not create a database, does not write timer history to storage, and does not send it anywhere. Closing the app discards the current session. Uninstalling the app removes all app data from your device.
4. NETWORK AND THIRD PARTIES
Chrono has no network features. It contains no advertising SDK, analytics SDK, crash-reporting SDK, social login or third-party tracker. No data is shared with third parties because no data is collected.
5. PERMISSIONS
Chrono requests no runtime permissions. It does not access the internet, location, camera, microphone, contacts, storage or any other protected resource.
6. CHILDREN'S PRIVACY
Chrono is a general-purpose timing tool and is not directed at children. Because the app collects no data at all, it does not knowingly collect personal information from anyone, including children under 13.
7. YOUR RIGHTS
Since no personal data is collected or stored by us, there is no personal data to access, correct, export or delete. If you believe we hold data about you, contact us and we will investigate.
8. CHANGES TO THIS POLICY
If Chrono later adds a feature that changes these practices, this page will be updated before that feature is released, and the effective date above will change. Continued use after an update means you accept the revised policy.
